United Arab Emirates (UAE) developer Emaar Properties has claimed that their Burj Dubai commercial and residential tower, currently under construction, has become the world’s tallest building, reaching a height of 512.1 metres (or 1,680 feet) and 141 storeys.

The current official record holder, Taipei 101 of Taiwan, has a height of 508 metres and 101 storeys, and will retain the “tallest building” title for some time to come. The Council on Tall Buildings and Urban Habitat sets the criteria for achieving height records for buildings, and will not evaluate the Burj Dubai until construction is complete in late 2008. Although final height details have been kept secret by the developer, the Burj Dubai is expected to reach nearly 700 metres in height, with approximately 160 storeys.

The current record holder for the world’s tallest free-standing structure is the CN Tower in Toronto, Canada. It has a height of 553 metres. The Burj Dubai, therefore, would claim both records when it is completed.

Once the Burj Dubai is completed, it will have required 330,000 cubic metres of concrete, 39,000 tonnes of steel and 142,000 square metres of glass, according to Emaar Properties. The building will have 56 lifts (elevators) that can move at a rate of speed of 1.75 to 10 metres per second.

Dubai is undergoing a construction boom currently with the Burj Dubai as the planned centrepiece of a $US20 billion project, which will eventually realize some 30,000 apartments and boast the world’s largest shopping mall.

There have been criticisms of the working conditions for construction workers in the UAE. A majority of the estimated 500,000 construction workers in the UAE are foreign workers from India, Pakistan and Bangladesh.

In a 2006 report on the UAE’s treatment of migrant workers, entitled Building Towers, Cheating Workers, Human Rights Watch documented abuses in UAE such as, “extremely low wages, several years of indebtedness to recruitment agencies for fees that UAE law says only employers should pay, the withholding of employees’ passports, and hazardous working conditions that result in apparently high rates of death and injury.”

In October of last year, Human Rights Watch delivered specific recommendations to the UAE government for improvement of working conditions. The UAE government acted swiftly on the report and put in place several improvements, which were applauded by Human Rights Watch.

However, the salaries of migrant construction workers remain in the range from $106 to $250 per month, while the national average wage is over $2,000 per month. Trade unions remain illegal in the UAE.

West Indies have beaten England by 15 runs in the first Twenty20 international of their tour of England at The Oval, London, England.

The West Indian innings started off badly by losing Gayle early, however they turned their fortunes around with some attacking and aggressive cricket and posted a huge total of 208. A bigger total could have been posted if it had not been for a late innings batting collapse. England started their reply by getting off to a flyer, but lost some early wickets that slowed down the run-rate. Leading the charge was Paul Collingwood with a fast 79 with 5 4’s and 4 6’s. In the end, England fell short by 15 runs. Had they not have lost the early wickets, England would have probably won the match to take a 1-0 lead in the series. Instead, it is West Indies that have taken a 1-0 lead in the series.

Members of the All India Bank Employees Association have threatened to go on nation-wide strikes to express their unhappiness with the move to privatise banks, allowing foreign direct investment in the banking sector and outsourcing of services. The exact dates of the strike will be decided at the AIBEA national general council meeting to be held in Chennai on June 13 and 14. Speaking to press persons on Friday, C.H. Venkatachalam, secretary of the association, condemned the attempts to continuously `attack the financial and banking sector.’

The AIBEA was against the government’s intention to privatise public sector banks and the disinvestment of shares up to 49 per cent. In the past decade, a number of private sector banks had folded and hence, in the best interests of the investor, banks should continue to remain in the public sector, he said. Merging public sector banks into five or six big banks in order to enable them become global institutions dealing with international trade and business was a `retrograde’ idea, he charged. The total assets of all the 27 public sector banks in the country (less than U.S. $300 billion) were well below the assets of any top global bank, he added.

A robotic system at Stanford Medical Center was used to perform a laparoscopic gastric bypass surgery successfully with a theoretically similar rate of complications to that seen in standard operations. However, as there were only 10 people in the experimental group (and another 10 in the control group), this is not a statistically significant sample.

If this surgical procedure is as successful in large-scale studies, it may lead the way for the use of robotic surgery in even more delicate procedures, such as heart surgery. Note that this is not a fully automated system, as a human doctor controls the operation via remote control. Laparoscopic gastric bypass surgery is a treatment for obesity.

There were concerns that doctors, in the future, might only be trained in the remote control procedure. Ronald G. Latimer, M.D., of Santa Barbara, CA, warned “The fact that surgeons may have to open the patient or might actually need to revert to standard laparoscopic techniques demands that this basic training be a requirement before a robot is purchased. Robots do malfunction, so a backup system is imperative. We should not be seduced to buy this instrument to train surgeons if they are not able to do the primary operations themselves.”

There are precedents for just such a problem occurring. A previous “new technology”, the electrocardiogram (ECG), has lead to a lack of basic education on the older technology, the stethoscope. As a result, many heart conditions now go undiagnosed, especially in children and others who rarely undergo an ECG procedure.

Investigators examining the wreck of British Airways Flight 38, a Boeing 777 that crash landed short of the runway at London’s Heathrow Airport in the first hull loss of a 777, are examining the aircraft’s fuel system as a possible factor in the crash. No-one was killed as the scheduled flight from Beijing, China lost power during final approach on January 17.

136 passengers and 16 crew were on board when power was lost to the two Rolls-Royce engines about two miles from the runway, at a height of 600 feet. Autopilot and autothrottle were engaged at the time, the latter having just commanded an increase of thrust to the engines when power was lost. Co-pilot John Coward, in control at the time, was subsequently praised for being able to glide the disabled plane to within 1,000 feet of the runway, clearing a number of houses along the way.

Subsequent investigation has revealed that not only did the engines not fail simultaneously, but neither failed completely, contradicting initial belief. A preliminary report by the United Kingdom’s Aircraft Accident Investigation Branch (AAIB) stated that after the autothrottle commanded more thrust “The engines both initially responded but after about 3 seconds the thrust of the right engine reduced. Some eight seconds later the thrust reduced on the left engine to a similar level… Both engines continued to produce thrust at an engine speed above flight idle, but less than the commanded thrust.” This situation prevailed until impact.

On Wednesday the AAIB stated that they were examining “All possible scenarios that could explain the thrust reduction and continued lack of response of the engines.” However, it also went on to specifically mention attention to the jet’s fuel system, saying “This work includes a detailed analysis and examination of the complete fuel-flow path from the aircraft tanks to the engine-fuel nozzles.” The AAIB also ruled out the plane having completely run out of fuel, stating that there was “adequate fuel” in the tanks when the plane crashed. In addition to the fuel required to get to the target destination or emergency alternative airport – whichever is further – aircraft typically carry between thirty and forty-five minutes worth of extra fuel as a safety margin.

Possible scenarios being examined include fuel contamination, coming either from fuel taken on at Beijing or leakage from an unknown source. In particular, a heavy contaminant at the bottom of the tanks would explain a lack of earlier problems on the flight, as the fuel levels would only have become low in the final stages of the trip. Another possibility is that a central part of the fuel system developed a leak, reducing the amount of fuel available to the engines.

It is known that, according to the AAIB, “the autothrottle and engine-control commands were performing as expected prior to, and after, the reduction in thrust,” suggesting that all software in the aircraft was functioning correctly and rendering a software failure unlikely, although this possibility also remains under investigation.

Tuesday, March 15, 2005A federal jury found Bernard Ebbers guilty on all nine counts in an indictment for fraud, conspiracy and false regulatory filings. The verdict was handed down by a New York jury after 8 days of deliberation on the former WorldCom CEO and mastermind behind the accounting scandal that brought down the telcom giant.

AP writer Erin McClam reported that when the verdict was announced, “Ebbers’ face reddened.”

Sentencing is set for the second Tuesday of next week when he could receive 85 years in prison for the conviction.

Ebbers who took the stand in his own defence, said he left the details of the company’s accounting to others and that he had no knowledge of shady practices. But Scott Sullivan, the ex-chief financial officer of the company and key prosecution witness, directly linked Ebbers to the fraud. Sullivan agreed to co-operate with prosecutors in the hopes of receiving a lenient sentence for his own involvement in the scandal.

The fall of WordCom sparked a massive class action law suit by investors. The plunge in WorldCom’s stock changed the capitalized value of the company in the range of $11 billion as the scandal unravelled. Secuities fraud cases stemming from the suits will probably break new legal ground where the involvement of investment banks and public accounting firms who would normally check company irregularities will be called into legal question.

The president of Egypt has suffered a “devastating blow” after the country’s army announced they would not use force against their own people, who continue to protest against the government tonight. The news came hours after six journalists who reported on the protests were released from custody.

Hosni Mubarak yesterday announced a new cabinet, which does not include several figures who protesters largely do not approve of. Analysts have, however, suggested little had changed within the government; many positions, they say, are filled with military figures.

In a statement broadcast on state media in Egypt, the army said: “To the great people of Egypt, your armed forces, acknowledging the legitimate rights of the people … have not and will not use force against the Egyptian people.” A BBC correspondent in Cairo said the announcement meant it “now seems increasingly likely that the 30-year rule of Mr Mubarak is drawing to a close.”

“The presence of the army in the streets is for your sake and to ensure your safety and wellbeing. The armed forces will not resort to use of force against our great people,” the statement added. “Your armed forces, who are aware of the legitimacy of your demands and are keen to assume their responsibility in protecting the nation and the citizens, affirms that freedom of expression through peaceful means is guaranteed to everybody.”

Earlier today, six journalists from the independent news network Al-Jazeera were released from custody after being detained by police. The U.S. State Department criticized the arrests; equipment was reportedly confiscated from the journalists.

Egyptian officials yesterday ordered the satellite channel to stop broadcasting in the country. Al-Jazeera said they were “appalled” by the government’s decision to close its Egyptian offices, which they described as the “latest attack by the Egyptian regime to strike at its freedom to report independently on the unprecedented events in Egypt.”

In a statement, the news agency added: “Al-Jazeera sees this as an act designed to stifle and repress the freedom of reporting by the network and its journalists. In this time of deep turmoil and unrest in Egyptian society it is imperative that voices from all sides be heard; the closing of our bureau by the Egyptian government is aimed at censoring and silencing the voices of the Egyptian people.”

On Friday, Wikinews reported the government had shut off practically all Internet traffic both out of and into the nation, as well as disrupting cellphone usage. A spokesperson for the social networking website Facebook said “limiting Internet access for millions of people is a matter of concern for the global community.”

A reported 50,000 campaigners, who are demanding the long-time leader step down and complaining of poverty, corruption, and oppression, filled Tahrir Square in Cairo today, chanting “We will stay until the coward leaves.” It is thought 100 people have so far died in the demonstrations. Today there have been protests in Suez, Mansoura, Damanhour, and Alexandria.

Speaking to news media in the area, many protesters said the new cabinet did little to quell their anger. “We want a complete change of government, with a civilian authority,” one said. Another added: “This is not a new government. This is the same regime—this is the same bluff. [Mubarak] has been bluffing us for 30 years.”

In Tahrir Square today, protesters played music as strings of barbed wire and army tanks stood nearby. Demonstrators scaled light poles, hanging Egyptian flags and calling for an end to Mubarak’s rule. “One poster featured Mubarak’s face plastered with a Hitler mustache, a sign of the deep resentment toward the 82-year-old leader they blame for widespread poverty, inflation and official indifference and brutality during his 30 years in power,” one journalist in the square reported this evening.
